@Stormy Solved recompiling PD after deleting the one installed from community repo.

I need some help for a problem I can not solve...

I installed PD 0.4.7.1 in Arch Linux.
It works (almost) everything.

I've created a "pd-externals" directory - nested in a number of other folders in Home - to keep the extra libraries.
I added the path.
Then I downloaded and installed via Deken: libdir, cyclone, Gem.

Libdir and cyclone work smoothly, so the whole system should be correct.
Gem, however, always returns "Gem can not load library".

I get the same result by moving Gem to any other possible location (usr/lib/pd/extra - /usr/local/lib/pd/extra/ - /home/USERNAME/pd-externals - etc. etc.).

Of course, I should work with Gem ...
